IPC: H04M3/00
Filed: 1991-12-25
Abstract: PURPOSE: To provide a credit card call method and device strong against faults. CONSTITUTION: This device and method which can establish connections between a cell source telephone 2 and cell destination telephones 40 and 41 in accordance with a call destination telephone number discriminated by a credit card(CC) of a person concerned to a call are constituted of connection data links 1050 to 1054 to databases 50 to 54 which CC companies discriminated by a CC number received from persons concerned to calls maintain. A data link transmits the received CC number from a telephone network 1 to the data base of the discriminated CC company from a telephone network 1 and receives a decision related to availability of the CC.  An NCP 10 monitors transmission and reception on data links; and if it is judged that some operation abnormality has occurred in a data base, the telephone network is controlled to transmit a report to the person concerned with the call who uses the CC issued by the CC company which maintains this data base, and call operation in the telephone network interrupted because of a fault is rejected.

Title: Closed type electromotive compressor
Inventor: TOYODA NORIHIKO
IPC: F04B39/12
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To provide a closed type electromotive compressor making a deformation of a frame to the minimum by a method not depending on a rigidity strenthening and having a high efficiency though the frame is deformed and a cooling gas leak from the compression mechanism and an efficiency reduction are caused since a stator core is not uniformly deformed when the frame of the compressor is tightened to the stator core of the electric motor by a bolt in the closed type electromotive compressor in which a compression mechanism and an electric motor are directly connected and are accommodated in a closed container. SOLUTION: A contact seat 1d of a circular shape or a multigonal shape such as a pentagonal or more shape having a diameter 1.5-3 times that of a bolt 4 is provided on a contact portion of a frame 1 of a compression mechanism with a stator core 3 of an electric motor by a bolt tightening, i.e., a periphery of a hole of the bolt 4. Since the outer diameter of the contact seat 1d is small, a bending moment M received by the frame 1 is extremely small even in the case where a deformation of the stator core 3 is not uniform in a periphery direction of the bolt 4 and the deformation of the frame 1 is reduced. Thereby, a cooling gas leak, a service life and an efficiency lowering of the compression mechanism are reduced.
